Media Mail vs BPM for comics

[Warlord]

I found an interesting doc on the USPS Postal Explorer web site. On page 23 there's an example that cites comic books. I'd like to get this example clarified. The example cites a business selling rare and used books. Says most of the product is comic books. Then mentions comic books can go as flats. Next it says that when shipping books that the seller can use a variety of services including BPM and Media. The references to comic books as books, or books as comic books are used loosely and perhaps interchangeably. I did the Contact Us feedback thing from this web site probably 6-8 weeks ago asking for clarification and never got a response. Anyone know how to get an authoritative clarification on this example?

 

 

"Darren Bailey, the owner of an online rare and used book business in

Pittsburgh, has decided that the speed and ease of retail services provide

the best solution for his mailing needs.

...

A large portion of Darren’s mailing is comic books, which can

be mailed as flats, but he also sells bound books, some of which cannot

be mailed as flats because of their size and shape. He has the option

of sending the books by Express Mail, Priority Mail, First-Class Mail

(13 ounces or less), Parcel Post, Bound Printed Matter, or Media Mail."
